有没有办法退出Greasemonkey脚本？ [英] Is there a way to exit a Greasemonkey script?

问题描述

我知道您可以使用 return; 从Greasemonkey脚本返回，但前提是您不在另一个函数中。例如，这不起作用：

I know that you can use return; to return from a Greasemonkey script, but only if you aren't in another function. For example, this won't work:

// Begin greasemonkey script
function a(){
    return; // Only returns from the function, not the script
}
// End greasemonkey script

是否有内置的Greasemonkey函数可以让我从脚本的任何地方停止执行脚本？

Is there a built in Greasemonkey function that would allow me to halt execution of the script, from anywhere in the script?

谢谢，

推荐答案

是的，你可能会做类似的事情：

Yeah, you can probably do something like:

(function loop(){
    setTimeout(function(){
        if(parameter === "abort") {
            throw new Error("Stopped JavaScript.");
        }
        loop();
  }, 1000);
})(parameter);

您可以通过将变量参数的值设置为中止来简单地中止脚本，这可以是一个常规变量或Greasemonkey变量。如果它是Greasemonkey变量，那么您可以使用Firefox中的about：config直接通过浏览器修改它。

You can simply abort your script by setting the value of variable parameter to abort, this can either be a regular variable or a Greasemonkey variable. If it's a Greasemonkey variable, then you can modify it directly through the browser using about:config in Firefox.
